Method of fabricating cathode for lithium ion secondary battery by recycling cathode active materal and lithium ion secondary battery fabricated thereby

The present invention relates to a method for fabricating a cathode for a lithium ion secondary battery by recycling an active material, and a lithium ion secondary battery including a cathode fabricated thereby. The method according to the present invention includes: carbonizing a binder existing in a cathode scrap of a lithium ion secondary battery by heat treating the cathode scrap of the lithium ion secondary bat tery; collecting a cathode active material from the cathode scrap of the lithium ion secondary battery; and forming a cathode for a lithium ion secondary battery without adding a conductive material to the collected cathode active material. According to the present invention, a lithium ion secondary battery which is environmentally friendly, economical, and capable of reducing manufacturing cost can be implemented.
